Also conflicts with relaxation-only variables are not generated at the moment. Relaxation-only variables do not appear in the objective.

◆ SCIPvarMarkRelaxationOnly()
| void SCIPvarMarkRelaxationOnly | ( | SCIP_VAR * | var | ) |
marks that this variable has only been introduced to define a relaxation
The variable must not have a coefficient in the objective and must be deletable. If it is not marked deletable, it will be marked as deletable, which is only possible before the variable is added to a problem.

creates and captures problem variable; if variable is of integral type, fractional bounds are automatically rounded; an integer variable with bounds zero and one is automatically converted into a binary variable;
- Warning
- When doing column generation and the original problem is a maximization problem, notice that SCIP will transform the problem into a minimization problem by multiplying the objective function by -1. Thus, the original objective function value of variables created during the solving process has to be multiplied by -1, too.
- Returns
- SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.
- Precondition
- This method can be called if
scipis in one of the following stages:
- Note
- the variable gets captured, hence at one point you have to release it using the method SCIPreleaseVar()
- Parameters
-
scip SCIP data structure var pointer to variable object name name of variable, or NULL for automatic name creation lb lower bound of variable ub upper bound of variable obj objective function value vartype type of variable initial should var's column be present in the initial root LP? removable is var's column removable from the LP (due to aging or cleanup)? vardata user data for this specific variable
